TW420802B - Pasting method for positioning and device of optical disc protection film - Google Patents

Abstract

A pasting method for positioning of the protection film of optical disc, the main purpose of which is to paste the film on the front and back side of the optical disc to prevent the important data in the optical disc from being damaged by accidental worn away. It mainly comprises two steps by using a pasting tool with a soft planar bottom layer and cylinder which can be pressed down and can automatically return to the original position. One of the step is to put one layer of complete back-glued hollow cylindrical protection film on the pasting tool, and then put the optical disc on the cylinder upside down so that the completely back-glued protection film is pasted to the printed surface of the optical disc after the cylinder is pressed down. Another step is to put the hollow circular protection film with its inner rim portion back-glued on the cylinder of the pasting tool, and then put the optical disc on the cylinder faced up to paste the protection film which is back-glued on its inner rim on the read-write face of the optical disc after the cylinder is pressed down. After these two steps, the front and back sides of the optical disc is prevented from being damaged of worn away or scratching by the protection film. Furthermore, the present invention also provides a protection film which can be pasted on both sides of the optical disc and a novel pasting tool.
